Abstract
A process for the production of a polymer composition comprising photopolymerizing at least one vinyl compound in the presence of a photoinitiator comprising at least one photosensitizer and at least one reducing agent selected from N-alkyl-pyrazole, N-alkyl-triazole, N-alkyl-tetrazole, N-aryl-benzotriazole, N-aryl-pyrazole, N-aryl-triazole, and N-aryl-tetrazole. Polymerizable materials and products produced by the process are also disclosed which are particularly suited as dental materials.
